Baltimore Sues Kalshi and Polymarket Over Alleged Illegal Betting Operations
Baltimore has filed a lawsuit against Kalshi and Polymarket, accusing them of facilitating illegal sports betting and operating prediction markets within the city.
Baltimore, MD, August 13, 2026 —
Baltimore city officials have initiated legal action against two financial platforms, Kalshi and Polymarket. The lawsuit, filed recently, alleges that both companies are facilitating illegal sports betting and operating unauthorized prediction markets within the city’s limits.
The core of the accusation centers on the nature of the financial instruments offered by Kalshi and Polymarket. Baltimore contends that these platforms enable users to bet on the outcomes of various events, including sporting contests, which the city deems to be in violation of state and local gambling laws.
The lawsuit claims that Kalshi and Polymarket have been operating these prediction markets without the necessary licenses or regulatory oversight required for such activities. City authorities are seeking to halt these operations and potentially impose penalties on the companies for their alleged non-compliance with existing regulations.
Details regarding the specific types of events available for prediction on the platforms, the extent of user engagement within Baltimore, and the precise legal statutes the companies are accused of violating were not fully detailed in the initial summary. Furthermore, the specific outcomes sought by the city, such as injunctions or financial penalties, and the contractor’s name were not provided.
Kalshi is an exchange that allows users to trade on the outcome of future events, while Polymarket operates as a decentralized prediction market. Both platforms have previously faced scrutiny regarding their business models and regulatory status in different jurisdictions.
The legal action by Baltimore adds another layer to the ongoing debate surrounding the regulation of prediction markets and their classification as either forms of financial trading or gambling. The outcome of this lawsuit could have implications for how similar platforms are treated and regulated in other cities and states.
The lawsuit’s filing marks a significant step by a major U.S. city to challenge the operations of these increasingly popular online platforms. The city’s legal team is expected to present evidence supporting its claims that the activities conducted on Kalshi and Polymarket constitute illegal gambling.
As of the latest information, the fine amounts and the specific permit status related to these operations were not provided. The timeline for the legal proceedings and any initial court responses from Kalshi or Polymarket have also not been detailed.
